Concerning the loss leader, that is correct. I should say from my Costco experience, I also got my duct glands checked. I don't remember getting that at Target/Lenscrafter the previous years. It was a few years since my last exam, so my memory could be wrong. I believe the tear duct check is a loss leader. Most people have dry eyes (Meibomian Gland Dysfunctio) if you work in front of a computer all day. I have it and saw an actual ophthalmologist before so I knew all about it. It cost $$ so I was surprised the optometrist did it as part of the checkup. If you want to get your dry eyes fixed you have to 'melt' the clogged ducts and it cost $300 for the cheapest treatment. $900 for the one that works best (Lipiflow). The treatment isn't permanent so you gotta go back every year for the $300 treatment and every 3 for the $900. Since the Costco optometrist can't make money from lens, I guess they make money from dry eye treatment. Also he gave me an option to dilate my pupils or he has a fancy imaging machine. The imagine machine costs $45...I opted for the imagine machine grin. One last point - the Costco optometrist has a fancy digital goggles to check your vision. Another commenter posted that it's a waste of an education for an eye vision check. The goggles show the letters to read (it's not projected on a wall) and has lenses embedded within it. With a keystroke on the computer, it changes the lens. He really just asks "which ones looks better" and hits the keyboard. I was done in a minute.
